我正在尝试使用tomcat连接到HBASE并遇到以下错误。当我运行Hbase时，它的工作正常。

以下是xml配置路径

  <configuration>
   <property>
     <name>hbase.rootdir</name>
     <value>hdfs://localhost:9000/hbase</value>
     <description>The directory shared by region servers.
     </description>
   </property>
   <property>
      <name>dfs.replication</name>
      <value>1</value>
      <description>The replication count for HLog and HFile storage.
      </description>              
   </property>
  </configuration>

Answer 1

该异常清楚地表明在类路径中找不到类org.apache.hadoop.hbase.filter.Filter。请在tomcat中将hbase-X.X.X.jar添加到应用程序的类路径中。请确保使用正确版本的hbase jar文件。

Answer 2

在tomcat的lib目录中复制hbase - * .jar并尝试重新运行。
